“…Furthermore, it is often very demanding to separate electronic from topographic features in STM [44], as well as to distinguish the chemical sensitivity of changing tip apexes towards different surface sites, both in STM and AFM. In a stable imaging mode typically only one type of species is imaged on the sample surface, either the anionic or the cationic site, depending on the actual tip configuration.…”

Determining the structure of amorphous materials used to be challenging due to the complexity of this material class. Despite many attempts to resolve amorphous materials by various diffraction methods as well as scanning probe methods, no-one has yet been able to carry out atomic imaging and to clearly identify the structure of amouphous materials. Only modern preparation methods in combination with advanced scanning tunneling and atomic force microscopy have succeeded in decrypting the everyday material glass. A bilayer silicate film on a ruthenium single crystal has been developed at the Fritz-Haber Institute. On the atomic level, this film is flat and ideal for using scanning probe microscopy. For the first time a clear image of an amorphous material has been obtained which allowed for the derivation of atomic sites and a ditailed analysis from real space coordinates. The text book example of the vitreous silica struture proposed by William Zachariasen in 1932 has thereby finally been verified

“…It is not surprising since MGs are topologically disordered, its surface is not expected to exhibit significant deviation in structure from the bulk. The few available properties from the past are mostly related to the study of surface morphologies: a roughening transition was found in some vapor-deposited MGs [12][13][14][15][16] and a recent AFM examination of bulk MGs showed surface striation [17]. Many basic questions, therefore, still remain unanswered.…”
